Technical Field

In the air rifle according to the invention, the feed of the ammunition into the barrel is enabled to take place automatically. Owing to the clip being placed every time the rifle is cocked, the possibility is provided to transfer the ammunition to the barrel without the touch of hands and to perform the successive shots in the form of quick fire.

Another feature of the rifle according to the invention is that it constitutes an alternative for the rifles that operate on the pre-charged pneumatics (PCP). Moreover, since the rifle according to the invention automatically charges air every time it is cocked, it is capable of operating for a long time without the need for an air cylinder, a pump or another accessory which would be required by PCP rifles. This invention concerns in particular a weapon structure, which eliminates, owing to the clip placed on the weapon, the necessity for the user to perform the feed every time a shot is to be made in the break barrel and bottom cocking type air rifles and which automatically transfers the ammunition in the clip to the barrel every time the weapon is cocked. The break barrel and bottom cocking type air guns have been known for a long time and they operate based on the principle of cocking of the rifle by way of breaking the barrel or an auxiliary arm, the placement of the ammunition by the user and reclosing of the barrel or the cocking lever to bring the rifle into a state ready for firing.

Prior Art All such functions are traditionally difficult and time-consuming. This situation has led the users to prefer the rifles operating on the pre-charged pneumatics ( PCP) .

The PCP rifle embodiments according to the state of the art, which have been in use until the present, involve the presence of a clip. Such weapons generally have a complicated and expensive structure. Since they operate on the pressure of the pre-charged air, the drawbacks such as the drop of the air pressure in the cylinder following every shot, the complete depletion of the air in the cylinder and the necessity to recharge the tube with air lead to the customer dissatisfaction. Moreover, as a great number of components are used in such applications, the low reliability and a difficult to maintain structure are encountered.

The aim of this invention is to eliminate the aforesaid shortcomings of the practices of the state of the art, obtain an air rifle mechanism with clip having high reliability, avoid the complicated structure to achieve simplicity and thus realize a weapon structure that provides any user with the possibility of easy use and maintenance.

Brief Description of the Invention

Within the scope of this aim, the object of this invention is to provide the capability to perform successive shots by giving the users the possibility to automatically feed the ammunition without the touch of hands owing to the placement of a clip in the air rifle. Another object of this invention is to achieve an air rifle structure with a clip having an everlasting capacity of air pressure by way of enabling the air, which is necessary for the rifle to perform a shot, to be automatically charged into said rifle every time the weapon is cocked. Another object of this invention is to achieve an air gun structure which, unlike the PCP rifles, is capable of operating without the need for a cylinder charged with air, an air pump and a filling apparatus.

Another object of this invention is to achieve the customer satisfaction with a new generation air gun far different from the conventional guns owing to the advantages that said air gun has a clip that allows the automatic feed of the ammunition and that an everlasting air pressure is obtained by way of the air necessary for the shot being automatically charged in the air chamber every time said gun is cocked.

In order to achieve the aforesaid objects, as will be seen later in the description, a moving air chamber is placed into a cylindrical carrier body, an air piston, a spring guide and a return spring are placed into said moving air chamber and the body is closed by a rear cover. A picatinny rail and a back sight are positioned in the upper part of the carrier body, a clip seat is made at a location near the end section and a clip is positioned in said seat. The barrel is mounted at the other end of the body and a front sight is positioned at the far end of the barrel. In addition, on the barrel side, the weapon has a cocking lever, one end of which is fitted in the carrier body and the other end of which is fitted in a seat in the front sight, said cocking lever being arranged in a way to engage the lower portion of the barrel. Moreover, this rifle has an action arm, which is mounted such that one end thereof engages the cocking lever and the other end thereof engages the seat in the moving air chamber. Finally, the trigger assembly and a piston safety are fitted on the carrier body to achieve the completed structure of the air rifle with clip.

This invention is focused on the positioning of the equipment, which are necessary for the air rifle mechanism with clip to perform its functions, in a robust and reliable manner on the body.

Another object intended to be achieved with this invention is to obtain a second safety mechanism through the automatic locking of the rifle piston every time the rifle is cocked, owing to the piston safety system positioned on the carrier body in addition to the trigger safety.

The invention thus aims to create the customer satisfaction by minimizing in this manner the likely problems to achieve a highly reliable weapon structure.

The parts on the figures are assigned with reference numerals in order to enable a better understanding of the invention. The following description will be provided along with these reference numerals so that the invention may be clearly understood.

The carrier body (1) is formed by a combination of five components. The body tube (2) is a cylindrical tube with a connection screw (7) opened on one end. The other end of the tube comprises the body rear cover (37) retainer hole (16) and the trigger assembly (83) connection holes (18), the section of the tube near the midpoint thereof comprises two holes 2 (13) for positioning the piston safety body (63) and there is also present at the same location a channel 1 (14) for engaging the lugs (73) shown on the piston safety sheet (64). In the top section, the hole 3 (15) for positioning the picatinny rail (4) is made, and on the same surface, the seat 1 (12) suitable for enabling the connection of the back sight (79) is opened. The bottom section contains the channel 2 (21) that carries and guides the action arm (51) during the cocking and closing of the rifle.

The other component part is the body cap (3). A nut-shaped threaded cavity (8) is made at one end of the cap to enable the assembly of said cap to the body tube (2). At the other end of the cap, there is present the barrel seat (10) for positioning the rifle barrel (74). A clip seat (9) is made in the middle section of the cap to enable the clip (78) to be fitted and a hole 1 (11) for joining the cocking lever (40) is opened in the bottom section.

The picatinny rail (4) is the part that bears the dovetail channels so that a scope and the similar accessories may be fitted. The bottom section of the rail comprises the protrusion 1 (20), which engages the hole 3 (15) on the carrier body (1) to enable the positioning of the rail.

Another component is the stock connection bush (5). It is in the form of a cylindrical piece and it comprises in the middle section thereof the seat 2 (17) intended for fitting the front damper plastic (82). Said stock connection bush (5) enables the rifle to be coupled with the stock (84).

Another component that constitutes the carrier body (1) comprises the trigger assembly sheets (6). These are present in the form of two "L"-shaped pieces. They bear the trigger assembly (83) connection holes (18). The crimped ends (19) are present on one side of the trigger assembly sheets (6). The crimped ends (19) are mounted in such a way that they will press the rear damper plastic (82) positioned into the stock while the rifle is being fitted in the stock (84).

The last part constituting the carrier body (1) is the front damper bush (92). It is positioned into the seat 2 (17) in the stock connection bush (5) on the carrier body (1). It is hollow in the middle section thereof and the screw that couples the stock (84) with the rifle passes through this hole during the assembly.

The above-mentioned rear damper plastic (82) and front damper bush (92) absorb the shocks generated by the recoil that occurs during a shot, thereby minimizing the level of damage to the weapon mechanism. They provide the users with the possibility of performing more comfortable and safer shots.

While the carrier body (1) of the air rifle with clip according to the invention is being formed, first the connection screw (7) on the body tube (2) is fitted in a way to engage the threaded cavity (8) on the body cap (3). Then, the picatinny rail (4), trigger assembly sheets (6) and stock connection bush (5) are positioned in their respective locations and joined by means of the welding process. Finally, the front damper bush (92) is fitted in the seat 2 (17) on the stock connection bush (5) to complete the illustrated structure of the carrier body (1) (Figure 3). The first and most important component that constitutes the air rifle with clip according to the invention is the carrier body (1). All the other components are positioned in and on the carrier body (1) to achieve a simplified and robust structure. Another member that constitutes the rifle is the moving air chamber (22). It is a structure formed by a combination of a cylindrical air chamber tube (23) and a tube cover 1 (24).

The air chamber tube (23) is in the form of a cylindrical tube with a cover 1 (24) connection screw (25) on one end thereof. The other end thereof includes the seat 3 (28) for fitting the action arm (51) and the seat 4 (29) disposed at an angle of 90° with respect to the seat 3 (28) for fitting the piston safety sheet (64).

Another component part that constitutes the moving air chamber (22) is the tube cover 1 (24). The cover includes at one end thereof a threaded cavity 2 (26) for enabling said cover to be coupled with the air chamber tube (23). The other end of the cover includes a cylindrical protrusion (93), the middle section of which protrusion includes the hole 4 (27) intended for the transfer of air.

While the moving air chamber (22) is being formed, the threaded cavity 2 (26) on the cover 1 (24) is engaged with the connection screw (25) on the air chamber tube (23), thereby obtaining an integrated structure (Figure 4).

The other members constituting the air rifle with clip are the piston (30) and the piston gasket (31). The piston (30) is in the form of a cylinder that is bored on the inside so that it would not explode. A recess (32) with a form suitable for fitting the piston gasket (31) is present on one end of the piston. The lower section of the piston includes a channel 3 (33) to ensure that it will not be affected by the movements of the action arm (51) during the cocking and the closing of the rifle. In addition, the cavity 1 (34) is formed in order to ensure that the piston safety sheet (64) does not contact the piston (30) while the rifle is performing its functions. During the assembly, the piston gasket (31) is fitted on the recess (32) formed on the piston (30), thereby joining the piston (30) and the piston gasket (31) as an integrated unit.

Another member that constitutes the air rifle with clip according to the invention is the cocking lever (40). The cocking lever (40) is formed by way of the coupling of two parts, namely the cocking lever shaft (41) and the cocking lever sheet (42), with the help of the rivets (43) in the form of an integrated unit.

A cavity 2 (44) is disposed in the middle section of said cocking lever shaft (41). The other end thereof includes a piece that is made thin by way of uniform combing and that comprises the rivet holes (45) on the surface.

The cocking lever sheets (42) are made by way of subjecting the same to a press according to the desired form. They comprise thereon two holes 5 (46) intended for enabling said sheets to be coupled with the cocking lever shaft (41). Also on the same side, there is present the hole 6 (47) where the action arm is fitted. On the other end, there is present the hole 7 (48) intended for enabling said sheets to be connected to the hole 1 (11) on the carrier body (1 ).

Prior to assembly, the cocking lever shaft (41) and the cocking lever sheets (42) are joined by means of the fixing rivets (43) to form the cocking lever (40).

Another component that constitutes the rifle is the action arm (51). It is made by bending the same according to the desired form. One end of said arm includes the hole 8 (52) intended for enabling said arm to be fitted in the hole 6 (47) on the cocking lever (40). The other end thereof includes the fitting section (53) arranged in a way to be positioned into the seat 3 (28) on the moving air chamber (22).

Another member that assists in the formation of the air rifle with clip is the front sight (54). The front sight (54) in the rifle according to the invention serves as a sight component while at the same time locking the cocking lever (40) at the desired position to prevent the same from performing involuntary movements. The front sight (54) is made by way of processing the same according to the desired form. It comprises thereon the barrel seat (77) for fitting the barrel (74). The lower section thereof includes the seat (59) for the cocking lever lock (55) that enables the cocking lever (40) to be positioned. There is also present the channel 4 (60) that allows the lock (55) to open and close.

The front sight (54) is formed by an integral combination of the cocking lever lock (55), lock spring (56), lock retainer screw (58) and retainer screw nut (57). The cocking lever lock (55) is in the form of a cylindrical tube that is partially bored on the inside. It comprises thereon the hole 9 (62) where the lock retainer screw (58) fits. The end section thereof includes the protrusion 2 (61), which serves to lock the lever in the desired position by engaging the hole 2 (44) on the cocking lever (40). When all these component parts are combined, the front sight (54) is formed. Another feature of the rifle is the presence of the piston safety system on said rifle. Both the trigger safety (38) and the piston safety are simultaneously employed in the rifle. The trigger safety (38) is coupled with the rear cover (37) of the carrier body with the help of the pin 1 (39). The piston (30) safety system is positioned on the carried body (1) in a way to correspond to the hole 2 (13) and the channel 1 (14). In this way, the risk of damage to the rifle parts, and more importantly, to the user is reduced to an almost non-existent level following the incidents that could occur.

The piston (30) safety system is formed by the safety body (63), piston safety sheet (64), safety spring (65), body retainer screws (66) and safety sheet retainer screw (67), which components constitute a whole.

The piston (30) safety body (63) is a piece that comprises thereon the channel 5 (68) extending from end to end, the body connection holes (70) made in a manner perpendicular to the channel 5 (68) and the spring seat (69). It also comprises in the top section thereof the hole (71) that enables the safety sheet to be positioned. During the assembly, it is secured on the carrier body (1) by means of the body retainer screws (66) using the hole 2 (13) on the carrier body (1).

The piston (30) safety sheet (64) is made with the desired form by way of subjecting the same to a press. It comprises thereon the fixing hole (72) intended for enabling said sheet to be secured to the safety body (63). One end of said sheet includes the lugs (73), which engage in the seat 4 (29) in the moving air chamber (22) every time the rifle is cocked to thereby prevent the involuntary movement of the moving air chamber (22). During the assembly of the same, the safety spring (65) is fitted in the spring seat (69) on the safety body (63) that has been fixed to the carrier body (1). Then, the sheet is positioned in a way to enter the channel 5 (68) on the safety body (63) and is enabled to assume its position on the safety body (63) with the help of the safety sheet retainer screw (67). Meanwhile, the lugs (73) at the end section of the sheet have entered the carrier body (1) and they are in a state capable of locking the moving air chamber (22) and thus the piston (30) once the rifle has been cocked.

Another component that constitutes the rifle is the barrel (74). The barrel (74) is a cylindrical piece the inside of which is bored end to end according to the desired caliber. The muzzle (76) has such a form enabling it to fit in the barrel seat (77) on the front sight (54). The other end of the barrel includes the threaded body (75) that allows the barrel to be fitted in the barrel seat (10) on the carrier body (1 ).

When forming the air rifle with clip according to the invention, first the rifle barrel (74) is mounted to the carrier body (1). The front sight (54) is placed at desired position on the muzzle (76). Then, the piston (30) is placed into the moving air chamber (22) and these two are together positioned into the carrier body (1 ). Next, the return spring (35) is fitted in a way to enter the piston (30). Then, the spring guide (36) and the body rear cover (37) are fitted and positioned into the carrier body (1) with the help of the retainer pin (80). Following these process steps, the trigger assembly (83) is secured on the carrier body with the help of the securing pins (81). Finally, the clip (78) is mounted on the carrier body to achieve the air rifle structure with clip according to the invention.

Another feature of the weapon according to the invention is that it comprises an adjustable cheekpiece (85). In this way, the user is provided with the ability to benefit from the same convenience during the use of the rifle by way of up and down adjustment of the cheekpiece (85) either when said user is employing the back sight (79) - front sight (54) or the scope and the similar optical instruments.

The cheekpiece (85) is a piece made in desired form with two adjusting pins 2 (88) thereon. It is positioned on the stock (84) with the help of the hole 11 (90) made on the butt portion of the stock (84). The adjusting nuts (87) and adjusting screws (86) are employed to keep the cheekpiece (85) in fixed state once it has been set in place. The stock (84) bears the hole 10 (89) where the adjusting nuts (87) are positioned. The adjusting nuts (87) comprise thereon the hole 12 (91) in which the pins 2 (88) on the cheekpiece (85) may engage. When mounting the cheekpiece (85) to the stock (84), first the adjusting nuts (87) are fitted in position into the hole 10 (89) on the stock (84). Then, the pin 2 (88) on the cheekpiece (85) is fitted in the stock (84) in a way to pass through the hole 11 (90) on the stock and the hole 12 (91) on the nuts and is fixed at the desired position by means of the adjusting screws (86).

In order to enable the air rifle with clip according to the invention to be better understood, we need to mention its operating principle.

First of all, the lock of the barrel (74) on the front sight is opened by way of pushing the same towards the muzzle (76) and the cocking lever (40) is enabled to become released so that it may move. When the rifle is started to be cocked by folding the cocking lever (40), the action arm (51) starts to move. Together with the action arm, the moving air chamber (22) and the piston (30) within said chamber also start to move in the same direction. The motion continues in this manner, and at the moment the cylindrical protrusion (93) on the moving muzzle has left the clip (78), the ammunition in the clip (78) comes into alignment with the barrel bearing. The cocking action is continued and is completed upon the piston (30) being fitted to the tab on the trigger assembly (83). Meanwhile, the return spring (35) within the piston (30) assumes the compressed position. When the piston (30) is being caught by the trigger assembly (83), both the trigger safety (38) and the piston (30) safety automatically become activated. The lugs (73) on the piston safety sheet (64) remain stationary as they engage the seat 4 (29) on the moving air chamber (22) and the cocking lover (40), which is connected thereto, also becomes unable to move. In this way, in case of problems such as the involuntary trigger squeeze or the fracture of the tab grasping the piston (30), the piston (30) and the moving air chamber (22) are prevented from rapidly moving forward; hence the cocking lever (40), which is connected thereto, is prevented from rapidly closing to cause damage to the rifle or the user.

Once the cocking action is completed, the user presses the piston safety sheet (64) to enable the locking lugs (73) on the safety to come out of the seat 4 (29) on the moving air chamber (22), thereby providing the moving air chamber (22) with the ability to move. The cocking lever (40) is rotated in the opposite direction to enable the moving air chamber (22) to return to its position prior to cocking. While the moving air chamber (22) is returning to its starting position, the cylindrical protrusion (93) on the same passes through the clip (78) to feed the ammunition into the barrel (74). The closing of the rifle is completed upon the cocking lever (40) being locked again by means of the cocking lever lock (55) on the front sight (54).

Now the rifle is in the state ready for a shot. When the trigger safety (38) is opened and the trigger is pulled, the piston (30), which becomes released from the tab in the trigger assembly (83), starts to rapidly move in the front direction within the moving air chamber (22) owing to the energy of the compressed return spring (35). Owing to the piston gasket (31) present on the piston, said piston causes the air in front of it to pass through the air passage hole 4 (27) on the moving air chamber (22), thus it enables the air to penetrate the ammunition and propel the same from the barrel (74), thereby enabling the shot action to take place. The cycle continues in this manner until all the ammunition in the clip (78) is consumed. The ability to continue the shot actions in the form of a quick fire by replacing the clips (78) is provided with the air rifle with clip according to the invention.
